GeForce 9400 GT 256MB vs GeForce GT 210

Intro

The GeForce 9400 GT 256MB has a GPU core clock speed of 550 MHz, and the 256 MB of GDDR2 RAM is set to run at 400 MHz through a 128-bit bus. It also is comprised of 16 Stream Processors, 8 Texture Address Units, and 4 Raster Operation Units.

Compare all that to the GeForce GT 210, which comes with a clock frequency of 589 MHz and a DDR3 memory frequency of 800 MHz. It also makes use of a 64-bit memory bus, and makes use of a 40 nm design. It is comprised of 16 SPUs, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210 31 Watts
GeForce 9400 GT 256MB 50 Watts
Difference: 19 Watts (61%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The GeForce GT 210 will be just a bit (approximately 7%) faster with regards to AF than the GeForce 9400 GT 256MB. (explain)

GeForce GT 210 4712 Mtexels/sec
GeForce 9400 GT 256MB 4400 Mtexels/sec
Difference: 312 (7%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 210 is superior to the GeForce 9400 GT 256MB, though only just barely. (explain)

GeForce GT 210 2356 Mpixels/sec
GeForce 9400 GT 256MB 2200 Mpixels/sec
Difference: 156 (7%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
